The last thing you want when you're crushing it on a gnarly downhill run is your hydration pack swinging all over the place. That won't be a problem with the Vaude Cluster 10+3 hydration pack.

External pocket with mesh organizer and coin compartment and side mesh pockets make it easy to access gear quickly

Included rain cover with light attachemtn

Padded hip belt with pocket gives you a perfect place to stash a gel or two

I have used this for mountain biking and hiking and am so impressed with it. I like the design of the bag, because it is very sleek and has a good amount of room, but doesn't have anything extra hanging off or added. I'm very impressed with it and the color is great.

This has been a great purchase, it has a lot of great features that make the product really enjoyable. One thing I did not like is that there are no instructions for some of the features, this is the first item of its kind I purchase, so I had to go to youtube to look for instructions on how to use the helmet holder and straps. I recently went on a snowboarding trip and I was really glad I had the product with me, I fell several times and nothing happen to the backpack. ***This is a day pack, you can put your wallet, keys, a layer or two, a pair of gloves and essential bike tools, dont think you will be able to a lot of stuff in it because you will be dissapointed*** So far I love it and would suggest you visit youtube to check out the great features it has
